If you can get a close up of the motor, if its Nissan or Toyota, I will be able to identify it for you. I'm a bit partial to the old Jap 4wd stuff, so if its a SD series or a TD series, then it will be obvious.
If its got an SD33/35 in it, if it runs just leave it there. They are generally bullet proof, even if they are a bit slow. I could tell you some nasty stories of how I treated an SD33 in a previous patrol and it never let me down. The patrol pretty much rusted around the motor...
The equivalent motor in a Nissan 6 petrol was either the L28 (from the 280ZX) or the P40. The P40 was the motor to have, but fuel economy was appalling. Torque was awesome, just plan your trip around servos.
As for a TD swap, they are still pretty expensive to buy even second hand as a good running unit, and they are not that fantastic on the fuel anyways. A GQ/GU wagon with the TD42 can expect anywhere from 13-14l/100km up to 18-20l/100km depending on configuration.
If you want to get extra performance from a TD42, then without spending big dollars to redo everything, then the gains are fairly nominal and fuel economy goes out the window. You find that as soon as you improve one thing, you find a choke point in the next point, and diesel mods are an expensive habit.
In their Std form, they are a bullet proof rock solid workhorse. Just don't expect anything else from it.
If you have to swap something in, your cheapest option in my opinion is a holden 304/ford 302 with the matching auto. You can pick up good running motors from a VR/AU or such for $500. A good TD42 could cost your upwards of $5000, plus the gearbox.
Also don't forget that the TD42 gearbox is a married box, which weighs a ton on its own. This just means you have to mount two gearboxes and the front output is un-used. Not a big deal, just an expensive extra option you won't need.
To be honest, I'm a diesel fan all day. If you have cash to burn on a project like this, I would chase down a Chev duramax diesel and the auto box to suit. Good fuel economy, plenty of power, sounds mint, pulls like a school boy with a stick book. Good all round, except for the cost to import one. A marginally cheaper option in the diesel scene is the 6.5l chev diesel, and auto, but the duramax is not significantly more in cost and 10 times the motor. I wouldn't recommend the Ford Powerchoke, for a whole bunch of reasons.
